I was wondering if you could cover a dummy cake with play dough? I really hate to cover dummy cakes with fondant just to throw it away. It's a lot of time and money compared to making playdough..just wonderng

no reason why not, unless it cracks when it dries. try a small dummy for a test. you should also try a color prone to fade, like lavendar or blue.

Will that Play-do smell dissipate after it dries?

It would be cheaper for you to make MMF and cover your dummy with that! I agree, I think the play-do would crack over time. I have 5 little children and I know what left out play-do looks like at my house! Not pretty!
